Semisynthetic analogs of Rapamycin (Macrolldes) being immunomodul ators 

10 This is a continuation-in-part of U.S. patent application Serial No. 

155,064, filed November 19, 1993. 

Technical Field 

The present invention relates to novel chemical compounds having 
15 immunomodulatory activity and synthetic intermediates useful for the 
preparation of the novel compounds, and in particular to macrolide 
immunomodulators. More particularly, the invention relates to semisynthetic 
analogs of rapamycin, means for their preparation, pharmaceutical compositions 
containing such compounds and methods of treatment employing the same. 

20 

Background of the Invention 

The compound cyclosporine (cyclosporin A) has found wide use since its 
introduction in the fields of organ transplantation and immunomodulation, and 
has brought about a significant increase in the success rate for transplantation 

25 procedures. Recently, several classes of macrocyclic compounds having potent 
immunomodulatory activity have been discovered. Okuhara et ai., in European 
Patent Application No. 184,162, published June 11, 1986, disclose a number of 
macrocyclic compounds isolated from the genus Streptomyces. 
Immunosuppressant FK-506, isolated from a strain of S. tsukubaensis, is a 

30 23-membered macrocyclic lactone represented by the formula shown below. 



WO 95/14023 



PCT/US94/12777 




FK-506 

5 Other related natural products, such as FR-900520 and FR-900523, which differ 
from FK-506 in their alkyl substituent at C-21, have been isolated from S. 
hygroscopicus yakushimnaensis. Yet another analog, FR-900525, produced by 
S. tsukubaensis, differs from FK-506 in the replacement of a pipecolic acid 
moiety with a proline group. Unsatisfactory side-effects associated with 

10 cyclosporine and FK-506 such as nephrotoxicity, have led to a continued search 
for immunosuppressant compounds having improved efficacy and safety. 

Rapamycin is a macrocyclic triene antibiotic produced by Streptomyces 
hygroscopicus, which was found to have antifungal activity, particularly against 
Candida albicans, both in vitro and in vivo (C. Vezina et al., J. Antibiot. 1975, 

15 28, 721; S. N. Sehgal et al., J. Antibiot. 1975, 28, 121; H. A. Baker et al., J. 
Antibiot. 1978,57, 539; U.S. Patent No. 3,929,992; and U.S. Patent No. 
3,993,749).

Rapamycin 



Rapamycin alone (U.S. Patent No. 4,885,171) or in combination with 
5 picibanil (U.S. Patent No. 4,401,653) has been shown to have antitumor activity. 
In 1977, rapamycin was also shown to be effective as an immunosuppressant in 
the experimental allergic encephalomyelitis model, a model for multiple 
sclerosis; in the adjuvant arthritis model, a model for rheumatoid arthritis; and 
was shown to effectively inhibit the formation of IgE-like antibodies (R. Martel 
10 et al., Can. J. Physiol. Pharmacol., 1977, 55, 48). 

The immunosuppressive effects of rapamycin have also been disclosed in 
FASEB, 1989, 3, 341 1 as has its ability to prolong survival time of organ grafts 
in histoincompatible rodents (R. Morris, Med. Sci. Res., 1989, 77, 877). The 
ability of rapamycin to inhibit T-cell activation was disclosed by M. Strauch 
15 (FASEB, 1989, 3, 341 1). These and other biological effects of rapamycin are 
reviewed in Transplantation Reviews, 1992, 6, 39-87. 

Mono-ester and di-ester derivatives of rapamycin (esterification at 
positions 31 and 42) have been shown to be useful as antifungal agents (U.S. 
Patent No. 4,316,885) and as water soluble prodrugs of rapamycin (U.S. Patent 
20 No. 4,650,803). 



WO 95/14023 



PCT/US94/12777 



-4- 

Fermentation and purification of rapamcyin and 30-demethoxy 
rapamycin have been described in the literature (C. Vezina et al. /. Antibiot. 
(Tokyo), 1975, 28 (10), 721; S. N. Sehgal et aL, J. Antibiot. (Tokyo), 1975, 
25(10), 727; 1983, 5(5(4), 351; N. L. Pavia et al., J. Natural Products, 1991, 
5 54(1), 167-177). 

Numerous chemical modifications of rapamycin have been attempted. 
These include the preparation of mono- and di-ester derivatives of rapamycin 
(WO 92/05179), 27-oximes of rapamycin (EPO 467606); 42-oxo analog of 
rapamycin (U.S. Patent No. 5,023,262); bicyclic rapamycins (U.S. Patent No. 

10 5,120,725); rapamycin dimers (U.S. Patent No. 5,120,727); silyl ethers of 

rapamycin (U.S. Patent No. 5,120,842); and arylsulfonates and sulfamates (U.S. 
Patent No. 5,177, 203). Rapamycin was recently synthesized in its naturally 
occuring enantiomeric form (K. C. Nicolaou et al., J. Am. Chem. Soc, 1993, 775, 
4419-4420; S. L. Schreiber, J. Am. Chem. Soc, 1993, 775, 7906-7907; S. J. 

15 Danishefsky, J. Am. Chem. Soc, 1993, 775, 9345-9346. 

It has been known that rapamycin, like FK-506, binds to FKBP-12 
(Siekierka,'J. J.; Hung, S. H. Y.; Poe, M.; Lin, C. S.; Sigal, N. H. Nature, 1989, 
341, 755-757; Harding, M. W.; Galat, A.; Uehling, D. E.; Schreiber, S. L. Nature 
1989, 341, 758-760; Dumont, F. J.; Melino, M. R.; Staruch, M. J.; Koprak, S. L.; 

20 Fischer, P. A.; Sigal, N. H. J. Immunol. 1990, 144, 1418-1424; Bierer, B. E.; 

Schreiber, S. L.; Burakoff, S. J. Eur. J. Immunol. 1991, 21, 439-445; Fretz, H.; 
Albers, M. W.; Galat, A.; Standaert, R. F.; Lane, W. S.; Burakoff, S. J.; Bierer, 

B. E.; Schreiber, S. L. J. Am. Chem. Soc 1991, 775, 1409-1411). Recently it has 
been discovered that the rapamycin/FKBP-12 complex binds to yet another 

25 protein, which is distinct from calcineurin, the protein that the FK-506/FKBP-12 
complex inhibits (Brown, E. J.; Albers, M. W.; Shin, T. B.; Ichikawa, K.; Keith, 

C. T.; Lane, W. S.; Schreiber, S. L. Nature 1994, 369, 756-758.; Sabatini, D. M.; 
Erdjument-Bromage, H.; Lui, M.; Tempest, P.; Snyder, S. H. Cell, 1994, 78, 35- 
43). 

30 Although some of these modified compounds exhibit immunosuppressive 

activity, the need remains for macrocyclic immunosuppressants which do not 
have the serious side effects frequently associated with immunosuppressant 
therapy. Accordingly, one object of this invention is to provide novel 



WO 95/14023 



PCT/US94/12777 



-5- 

semisynthetic macrolides which possess the desired immunomodulatory activity 
but which may be found to rninimize untoward side effects. 

Another object of the present invention is to provide synthetic processes 
for the preparation of such compounds from starting materials obtained by 
5 fermentation, as well as chemical intermediates useful in such synthetic 
processes. 

A further object of the invention is to provide pharmaceutical 
compositions containing, as an active ingredient, at least one of the above 
compounds. Yet another object of the invention is to provide a method of 
10 treating a variety of disease states, including post-transplant tissue rejection and 
autoimmune disfunction.

Example 188 
In vitro Assay of Biological Activity 
The immunosuppressant activity of the compounds of the present 
invention was determined using the human mixed lymphocyte reaction (MLR) 
5 assay described by Kino, T. et al. in Transplantation Proceedings, XIX(5):36- 
39, Suppl. 6 (1987). The in vitro immunosuppressant activity of the compounds 
of the present invention was determined in a one way allogeneic mixed leukocyte 
response (MLR) assay using rat lymph node and spleen cells, conducted as 
follows: Responder cells were obtained from the lymph nodes of Brown Norway 

10 rats (Harlan Sprague Dawley, Inc., Indianapolis, IN) and the stimulator cells 
were isolated from the spleens of Lewis rats (Harlan Sprague Dawley, Inc., 
Indianapolis, IN). 200-250 gram rats were sacrificed by asphyxiation with CO2 
and the popliteal and mesenteric lymph nodes or spleen were removed by sterile 
dissection. The tissue was placed in RPMI 1640 supplemented with 10% 

15 heat-inactivated fetal bovine serum, 2 mM L-glutamine, 50 (J.M 

2-mercaptoethanol, 50 units/mL penicillin G, and 50 ng/mL streptomycin 
(complete RPMI medium). After mechanically disrupting the tissue and 
allowing debris to settle at 1 x g, the suspended cells were aspirated. The cell 
suspensions were centrifuged 10 min at 400 x g and the responder cells 

20 resuspended in complete RPMI medium at 2 x 10 6 cells/mL. To remove red 

cells, the spleen cells were suspended in 0.14 M NH4CI/O.OI7 M Tris-HCl lysing 
buffer, pH 7.4, for 2 minutes, mixed with RPMI 1640, and centrifuged as before. 
The spleen cells were subsequently washed three times by centrifugation in 
RPMI 1640. To inhibit their abilty to proliferate, spleen cells were suspended at 

25 1 x 10 7 cells/mL in complete RPMI medium and incubated in the presence of 25 
|J.g/mL of mitomycin C for 30 minutes at 37 °C. The mitomycin C-treated spleen 
cells were washed three times by centrifugation in RPMI 1640 before being 
suspended in complete RPMI medium at 4 x 10 6 cells/mL. 

For the MLR, 1 x 10 5 lymph node cells were mixed with 5 x 10 5 

30 mitomycin C-treated spleen cells in 0.2 raL of complete RPMI 1640 and cultured 
in 95% air / 5% CO2 atmosphere for 120 hours at 37 °C. Test compounds were 
dissolved at 10 mM in dimethylsulfoxide, diluted in complete RPMI medium, 
and 25 u\L of the test compound was added to the lymph node cells before 
addition of the spleen cells. During the final 6 hours, the cells were labeled with

0.5 flCi per well of tritiated thymidine ( 3 H-TdR; DuPont NEN Research 
Products, Boston, MA). The cells were harvested by vacuum filtration onto 
glass fiber filters and the filter radioactivity measured with a MATRIX 9600 
direct beta counter (Packard Instrument Company, Meriden, CT). To calculate 
the compound concentration which caused 50% inhibition (IC 50 ) in an assay, the 
inhibition data was fit to a log-logistic linear function. 

The results of the assay, shown below in Table 1, demonstrate that the 
compounds tested are effective immunomodulators at nanomolar concentrations.

5 The compounds of the invention, including but not limited to those 

specified in the examples, possess immunomodulatory activity in mammals 
(especially humans). As immunosuppressants, the compounds of the present 
invention axe useful for the treatment and prevention of immune-mediated 
diseases such as the resistance by transplantation of organs or tissue such as 

10 heart, kidney, liver, medulla ossium, skin, cornea, lung, pancreas, intestinum 
tenue, limb, muscle, nervus, duodenum, small-bowel, pancreatic-islet-cell, etc.; 
graft-versus-host diseases brought about by medulla ossium transplantation; 
autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, 
Hashimoto's thyroiditis, multiple sclerosis, myasthenia gravis, type I diabetes 

15 uveitis, allergic encephalomyelitis, glomerulonephritis, and the like; and further 
infectious diseases caused by pathogenic microorganisms, such as HIV. In the 
particular cases of HIV- 1, HIV-2 and related retroviral strains, inhibition of T- 
cell proliferation will suppress the replication of the virus, since the virus relies 
upon the T-cell's proliferative functions to replicate. Further uses include the 

20 treatment and prophylaxis of inflammatory and hyperproliferative skin diseases 
and cutaneous manifestations of immunologically-mediated illnesses, such as 
psoriasis, atopical dermatitis, contact dermatitis and further eczematous 
dermatitises, seborrhoeis dermatitis, Lichen planus, Pemphigus, bullous

-139- 

augmention of chemotherapeutic effect, cytomegalovirus infection, particularly 
HCMV infection, anti-inflammatory activity, and so on. 

Additionally, compounds of the invention possess FK-506 antagonistic 
properties. The compounds of the present invention may thus be used in the 
5 treatment of immunodepression or a disorder involving immunodepression. 

Examples of disorders involving immunodepression include AIDS, cancer, senile 
dementia, trauma (including wound healing, surgery and shock) chronic bacterial 
infection, and certain central nervous system disorders. The immunodepression * 
to be treated may be caused by an overdose of an immunosuppressive 

10 macrocyclic compound, for example derivatives of 12-(2-cyclohexyl-l- 

methylvinyl)-13, 19,21,27 -tetramethyl- 1 l,28-dioxa-4-azatricyclo[22.3.1.0 4 <9] 
octacos-18-ene such as FK-506, or rapamycin. Overdosing of such medicants by 
patients is quite common upon their realizing that they have forgotten to take 
their medication at the prescribed time and can lead to serious side effects. 

15 The ability of the compounds of the invention to treat proliferative 

diseases can be demonstrated according to the methods described in Bunchman 
ET and CA Brookshire, Transplantation Proceed. 23 967-968 (1991); Yamagishi, 
et al., Biochem. Biophys. Res. Comm. 191 840-846 (1993); and Shichiri, et al., J. 
Clin. Invest. 87 1867-1871 (1991). Proliferative diseases include smooth muscle 

20 proliferation, systemic sclerosis, cirrhosis of the liver, adult respiratory distress 
syndrome, idiopathic cardiomyopathy, lupus erythematosus, diabetic retinopathy 
or other retinopathies, psoriasis, scleroderma, prostatic hyperplasia, cardiac 
hyperplasia, restenosis following arterial injury or other pathologic stenosis of 
blood vessels. 

25 Aqueous liquid compositions of the present invention are particularly 

useful for the treatment and prevention of various diseases of the eye such as 
autoimmune diseases (including, for example, conical cornea, keratitis, dysophia 
epithelialis comeae, leukoma, Mooren's ulcer, sclevitis and Graves' 
ophthalmopathy) and rejection of corneal transplantation.

When used in the above or other treatments, a therapeutically effective 
amount of one of the compounds of the present invention may be employed in 
pure form or, where such forms exist, in pharmaceutically acceptable salt, ester 
or prodrug form. Alternatively, the compound may be administered as a 



WO 95/14023 



PCTYUS94/12777 



-140- 

pharmaceutical composition containing the compound of interest in combination 
with one or more pharmaceutically acceptable excipients. The phrase 
"therapeutically effective amount" of the compound of the invention means a 
sufficient amount of the compound to treat disorders, at a reasonable benefit/risk 
5 ratio applicable to any medical treatment. It will be understood, however, that 
the total daily usage of the compounds and compositions of the present invention 
will be decided by the attending physician within the scope of sound medical 
judgement. The specific therapeutically effective dose level for any particular 
patient will depend upon a variety of factors including the disorder being treated 

10 and the severity of the disorder; activity of the specific compound employed; the 
specific composition employed; the age, body weight, general health, sex and 
diet of the patient; the time of administration, route of administration, and rate of 
excretion of the specific compound employed; the duration of the treatment; 
drugs used in combination or coincidental with the specific compound employed; 

15 and like factors well known in the medical arts. For example, it is well within 
the skill of the art to start doses of the compound at levels lower than required to 
achieve the desired therapeutic effect and to gradually increase the dosage until 
the desired effect is achieved. 

The total daily dose of the compounds of this invention administered to a 

20 human or lower animal may range from about 0.001 to about 3 mg/kg/day. For 
purposes of oral administration, more preferable doses may be in the range of 
from about 0.005 to about 1.5 mg/kg/day. If desired, the effective daily dose 
may be divided into multiple doses for purposes of administration; consequently, 
single dose compositions may contain such amounts or submultiples thereof to 

25 make up the daily dose. 

The pharmaceutical compositions of the present invention comprise a 
compound of the invention and a pharmaceutically acceptable carrier or 
excipient, which may be administered orally, rectally, parenterally, 
intracisternally, intravaginally, intraperitoneally, topically (as by powders, 

30 ointments, drops or transdermal patch), bucally, or as an oral or nasal spray. 

The phrase "pharmaceutically acceptable carrier" means a non-toxic solid, semi- 
solid or liquid filler, diluent, encapsulating material or formulation auxiliary of 
any type. The term "parenteral" as used herein refers to modes of administration 



WO 95/14023 



PCTVUS94/12777 



-141- 

which include intravenous, intramuscular, intraperitoneal, intrasternal, 
subcutaneous and intraarticular injection and infusion. 

Pharmaceutical compositions of this invention for parenteral injection 
comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions, 

5 dispersions, suspensions or emulsions as well as sterile powders for 

reconstitution into sterile injectable solutions or dispersions just prior to use. 
Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or 
vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, 
polyethylene glycol, and the like), carboxymethylcellulose and suitable mixtures 

10 thereof, vegetable oils (such as olive oil), and injectable organic esters such as 
ethyl oleate. Proper fluidity can be maintained, for example, by the use of 
coating materials such as lecithin, by the maintenance of the required particle 
size in the case of dispersions, and by the use of surfactants. 

These compositions may also contain adjuvants such as preservatives, 

15 wetting agents, emulsifying agents, and dispersing agents. Prevention of the 
action of microorganisms may be ensured by the inclusion of various 
antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol 
sorbic acid, and the like. It may also be desirable to include isotonic agents such 
as sugars, sodium chloride, and the like, Prolonged absorption of the injectable 

20 pharmaceutical form may be brought about by the inclusion of agents which 
delay absorption such as aluminum monostearate and gelatin. 

In some cases, in order to prolong the effect of the drug, it is desirable to 
slow the absorption of the drug from subcutaneous or intramuscular injection. 
This may be accomplished by the use of a liquid suspension of crystalline or 

25 amorphous material with poor water solubility. The rate of absorption of the 
drug then depends upon its rate of dissolution which, in turn, may depend upon 
crystal size and crystalline form. Alternatively, delayed absorption of a 
parenterally administered drug form is accomplished by dissolving or suspending 
the drug in an oil vehicle. 

30 Injectable depot forms are made by forming microencapsule matrices of 

the drug in biodegradable polymers such as polylactide-polyglycolide. 
Depending upon the ratio of drug to polymer and the nature of the particular 
polymer employed, the rate of drug release can be controlled. Examples of other 
biodegradable polymers include poly(orthoesters) and poly(anhydrides) Depot 



WO 95/14023 



PCT/US94/12777 



-142- 

injectable formulations are also prepared by entrapping the drug in liposomes or 
microemulsions which are compatible with body tissues. 

The injectable formulations can be sterilized, for example, by filtration 
through a bacterial-retaining filter, or by incorporating sterilizing agents in the 
5 form of sterile solid compositions which can be dissolved or dispersed in sterile 
water or other sterile injectable medium just prior to use. 

Solid dosage forms for oral administration include capsules, tablets, pills, 
powders, and granules. In such solid dosage forms, the active compound is 
mixed with at least one inert, pharmaceutically acceptable excipient or carrier 

10 such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such 
as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such 
as, for example, carboxymethylcellulose, alginates, gelatin, 
polyvinylpyrrolidone, sucrose, and acacia, c) humectants such as glycerol, d) 
disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca 

15 starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding 
agents such as paraffin, f) absorption accelerators such as quaternary ammonium 
compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol 
monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants 
such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, 

20 sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and 
pills, the dosage form may also comprise buffering agents. 

Solid compositions of a similar type may also be employed as fillers in 
soft and hard-filled gelatin capsules using such excipients as lactose or milk 
sugar as well as high molecular weight polyethylene glycols and the like. 

25 The solid dosage forms of tablets, dragees, capsules, pills, and granules 

can be prepared with coatings and shells such as enteric coatings and other 
coatings well known in the pharmaceutical formulating art. They may optionally 
contain opacifying agents and can also be of a composition that they release the 
active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, 

30 optionally, in a delayed manner. Examples of embedding compositions which 
can be used include polymeric substances and waxes. 

The active compounds can also be in micro-encapsulated form, if

suspending agents as, for example, ethoxylated isostearyl alcohols, 

15 polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, 

aluminum metahydroxide, bentonite, agar-agar, and tragacanth, and mixtures 
thereof. 

Topical administration includes administration to the skin or mucosa, 
including surfaces of the lung and eye. Compositions for topical administration, 

20 including those for inhalation, may be prepared as a dry powder which may be 
pressurized or non-pressurized. In non-pressurized powder compositions, the 
active ingredient in finely divided form may be used in admixture with a larger- 
sized pharmaceutically acceptable inert carrier comprising particles having a 
size, for example, of up to 100 micrometers in diameter. Suitable inert carriers 

25 include sugars such as lactose. Desirably, at least 95% by weight of the particles 
of the active ingredient have an effective particle size in the range of 0.01 to 10 
micrometers. 

Alternatively, the composition may be pressurized and contain a 
compressed gas, such as nitrogen or a liquified gas propellant. The liquified 
30 propellant medium and indeed the total composition is preferably such that the 
active ingredient does not dissolve therein to any substantial extent. The 
pressurized composition may also contain a surface active agent. ■ The surface 
active agent may be a liquid or solid non-ionic surface active agent or may be a 



WO 95/14023 



PCT/US94/12777

Intern^onai application No. 

PCT/US 94/ 12777 



Box I Observations where certain claims were found unsearchable (Continuation of item I of first sheet) 



This international search report has not been established in respect of certain claims under Article 17(2)(a) for the following reasons: 
1. Claims Nos.: 

because they relate to subject matter not required to be searched by this Authority, namely: 

Although claims 38-48 are directed to a method of treatment of the human/ 

animal body (Rule 39.1.(iv), the search has been carried out and based on 
the alleged effects of the compounds. 

2 ' ^ beaSsVthey relate to parts of the international application that do not comply with the prescribed requirements to such 
an extent that no meaningful international search can be carried out, specifically: 



be^se'they are dependent claims and are not drafted in accordance with the second and third sentences of Rule 6.4(a). 



Box II Observations where unity of invention is lacking (Continuation of item 2 of first sheet) 



This International Searching Authority found multiple inventions in this international application, as follows: 



1 . Q^j As all required additional search fees were timely paid by the applicant, this international search report covers all 

searchable claims. 

2. [""I As all searchable claims could be searches without effort justifying an additional fee, this Authority did not invite payment 

of any additional fee. 



3. A.s only some of the required additional search fees were timely paid by the applicant, 

' 1 covers only those claims for which fees were paid, specifically claims Nos.: 



this international search report 



4 I I No required additional search fees were timely paid by the applicant. Consequently, this international search report is 
1 1 restricted to the invention first mentioned in the claims; it is covered by claims Nos.: 



Remark on Protest [^] The additional search fees were accompanied by the applicant's protest. 

| | No protest accompanied the payment of additional search fees.
